  • Patent number: 12607233
    Abstract: A system includes a rotor shaft rotatable about an axis, a disconnect shaft nested at least partially within an interior of the rotor shaft, and a journal shaft selectively rotatably coupled to the disconnect shaft. A vibration damping mechanism is arranged between the rotor shaft and the journal shaft. The vibration damping mechanism includes a thrust journal bearing affixed to the rotor shaft and a thrust washer mounted to the journal shaft. A biasing mechanism is operably coupled to disconnect shaft to bias the thrust washer into frictional engagement with the thrust journal bearing.

  • Publication number: 20240313623
    Abstract: An electric machine rotor includes a rotor body configured to rotate about a rotation axis. A winding includes a plurality of end winding portions extending circumferentially over an axial end of the pole core. An anchor is woven into the end winding portions to inhibit movement of the end winding portions relative to the pole core. The anchor includes a first portion extending radially outward along a first row of the end winding portions. A second portion of the anchor extends axially from the first row, beyond a second row of the end winding portions to a third row of the end winding portions. A third portion of the anchor extends radially along the third row. A fourth portion extends axially between two of the end windings in the third row. A fifth portion of the anchor extends radially inward between the second row and the third row.

  • Patent number: 5946753
    Abstract: A combination cigar clipper and bottle opener having a substantially rectangular configuration with a fixed bottle opener at one end and a D-shaped handle at the other end. The D-shaped handle is attached to a blade which is slidably disposed within the hollow rectangular housing and is adapted for clipping off the end of a cigar. An aperture, through which cigars may be inserted for clipping off the ends, is positioned centrally to the rectangular housing.
